[PyMOL] Pseudoatom for a cavity

[kanika s. <ksh...@gm...>]

Dear PyMol Users,

I am struggling here two things.
1). I want to place a pseudoatom in the charge centre of a non aromatic
residue, like arginine.
2). Is it possible to place another pseudoatom in the centre of a cavity in
the protein? I am thinking how can I define the co ordinates of the
position where I wan t to place the pseudoatom?

​Thanks ​
